Rajaton: Finnish a cappella

Adapted from http://www.singers.com/jazz/rajaton.html:
I'm guessing that not a lot of people have heard the sound of finnish a cappella music, and it's time to change that, as far as I'm concerned. Vocal ensemble Rajaton, founded in autumn 1997, is a professional a cappella group with six singers (SSATBarB) most of whom have studied singing either at the Sibelius-Academy or at the Pop/Jazz Conservatory in Helsinki, Finland. They primarily perform music written for the group. As its name shows (rajaton = boundless), its musical scale ranges from sacred music to pop and from folk music to contemporary concert music. At the moment, their repertoire consists mostly of settings of texts by Finnish and foreign poets written for the ensemble by young Finnish choral composers. Rajaton also performs new arrangements of Finnish and foreign folk songs.

Give a listen to Mita kaikatat, kivonen? ("Wherefore Grumblest Thou, O Grindstone?") which I discovered via Said the Gramohpone blog.
